The manual for my Mark I says you can run EL34s in it so I pooped in a set. Since there is no bias switch in the Mark I they are biased pretty cold, .05 on my Bias Rite meter! Still, they actually sound pretty good in the amp. I'm a little confused by the manual though. It talks about using tweed power with 6V6 and EL34 tubes. I can understand this for the 6V6s, but shouldn't EL34s be able to take the 460 volts my Mark puts on the plates in full power mode?
